[Mapserver-users] Problem with LINEITEM and CLASS NAME

[Roger Truesdale]

I am running mapserv 3.6.6 with the following map that is listed below. 


Note the two lines marked by #-- in the TOWER layer.   One is for the
layer LINEITEM and the other for the class NAME.
When BOTH of these lines are commented out, a map of county boundries
appears with green circles for the tower locations.
This part works fine, but I want to use the TowerId field values  from
the dbf file as labels for the tower locations.  When I attempt to do
this by uncommenting only the LINEITEM line, I just get a blank screen
coming back with no error messages.  I checked that the LINEITEM value
TOWERID has the same case as in the dbf table. I also noticed that if I
leave the LINEITEM line commented out and uncomment the class NAME line,
then I also get a blank screen back.  Can anyone see what I am doing
wrong or what I may be missing?

Thanks.
